that sounds like it would be a complicated circuit. i obviously have a speed controller for each motor, but i would have to put it in front of every speed control, and it would not be something as simple as a comparitor circuit. it has to pe perportional, and not compare 2 items, but compare 4 items to each other item (the motors) but what i was asking when i said how may i create a governer, i meant "how do i build it" or "do you have a schematic" or that kind of thing. i understand that each motor would have to be sensed, most likely using a tachometer type light sensor.
